Abstract
A cutting device includes a movable blade and a stationary blade opposed to the movable blade across a sheet-like object to be cut. The movable blade is formed into a concave shape retracted inwardly from opposite end portions toward a central portion thereof. The stationary blade is formed into a straight line in parallel to the cut surface of the object. An angle of each of portions of the cutting edge on sides of the opposite end portions with respect to a cut surface of the object to be cut is larger than an angle of each of portions of the cutting edge on both sides of the central portion with respect to the cut surface.
